Jerami Dan Arang Sekam Padi Dapat Dijadikan Bahan Untuk Pembuatan Mulsa Organik, Karena Memiliki Kandungan Yang Dibutuhkan Tanaman. Penelitian Ini Bertujuan Untuk Mengetahui Pengaruh Mulsa Jerami Dan Arang Sekam Padi Terhadap Pertumbuhan Dan Hasil Tanaman Tomat. Penelitian Ini Dilaksanakan Dilahan Penelitian Fakultas Pertanian Universitas Borneo Tarakan Dari Bulan September - November 2018. Penelitian Ini Menggunakan Rancang Acak Kelompok (RAK) Dengan 1 (Satu) Faktor Yaitu Mulsa Jerami Dan Arang Sekam Padi Dengan 4 Perlakuan Dan 3 Ulangan Sehingga Didapatkan 12 Unit Percobaan, 4 Taraf Perlakuan Yaitu: M0 = Kontrol (Tanpa Pemberian Mulsa Jerami Dan Arang Sekam Padi), M1 = Pupuk Kandang 2 Kg/Bedeng, M2 = Mulsa Arang Sekam Padi 3 Kg/Bedeng, M3 = Mulsa Jerami Padi 3 Kg/Bedeng. Parameter Yang Diamati Yaitu Tinggi Tanaman (Cm), Diameter Batang (Mm), Jumlah Daun (Helai), Jumlah Buah Per Tanaman (Buah),Dan Berat Buah Per Tanaman (G). Data Yang Diperoleh Dianalisis Dengan Sidik Ragam Dan Jika Berpengaruh Nyata Dilakukan Uji Lanjut Dengan Uji Beda Nyata Terkecill (BNT) Pada Taraf 5%. Hasil Penelitian Menunjukkan Bahwa Perlakuan Pemberian Mulsa Jerami (M3) 3 Kg Secara Umum Memberikan Hasil Yang Berbeda Nyata Pada Parameter Tinggi Tanaman (4 MST), Diameter Batang (2,3,4 MST), Dan Jumlah Daun (3 MST) Sedangkan Pada Perlakuan Mulsa Arang Sekam Padi (M2) 3 Kg Memberikan Pengaruh Terbaik Pada Parameter Jumlah Buah Per Tanaman Sebesar 20.89 Buah Dan Berat Segar Buah Per Tanaman 35.06 G. Saran Perlu Dilakukan Penelitian Lebih Lanjut Menggunakan Kombinasi Mulsa Jerami Dan Arang Sekam Padi Dengan Takaran 3 Kg Pada Budidaya Tanaman.

Straw And Rice Husk Charcoal Can Be Used As Ingredient For Making Organic Mulch, Because It Has Nutrients Needed By Plants. This Study Aims To Determine The Effect Of Straw Mulch And Rice Husk Charcoal On The Growth And Yield Of Tomato Plants. This Research Was Conducted In The Field Of Research At The Faculty Of Agriculture, Borneo, Tarakan, University From September To November 2018. This Research Method Uses Randomized Block Design (RBD) With 1 (One) Factor, Namely Straw Mulch And Rice Husk Charcoal With Four Treatments And Three Replications So That There Are Twelve Experiment Units. Research Variables Were Analyzed In Variance And If Significant Effect Was Carred Out Further Testing With The Smallest Significant Difference Test (LSD), At The Level Of 5%. The Treatment Used Is M0 = Control (Without Mulch), M1 = Chicken Manure Two Kg /Plot, M2 = Mulch Rice Husk Charcoal Three Kg /Plot, M3 = Straw Mulch Three Kg /Plot. The Results Showed That The Treatment Of Straw Mulch (M3) 3 Kg Generally Gave Significantly Different Results On The Parameters Of Plant Height (Four Weeks After Planting), Stem Diameter (Two, Three, Four Weeks After Planting), And Number Of Leaves (Three Weeks After Planting) While The Treatment Of Rice Husk Charcoal Mulch (M2) 3 Kg Gave The Best Effect On The Parameters Of The Number Of Fruits Per Plant As Much As 20.89 Pieces And The Fresh Weight Of Fruit Per Plant. 35.06 G. Suggestion It Is Necessary To Do Further Research Using A Combination Of Straw Mulch And Rice Husk Charcoal With A Dose Of 3 Kg In Plant Cultivation.
